Apologies for the delay in posting this!
1. Consider two stars: one has an apparent magnitude of 2 and the other has an apparent magnitude of -1. Which star is brighter, and by what factor is it brighter? (That is, how many times brighter is it than the dimmer one?)
2. Consider the radio station DC101, which generates a signal operating at 101.1 MHz. (MHz means million Hz, or million vibrations per second.)
a. Where on the EM spectrum would you find this station?
b. What is the frequency, speed, and wavelength associated with this signal? You may have to calculate one of these answers - if you're not sure how to complete the calculation, at least show HOW to set it up.
3. Consider the blackbody radiation curve shown in class (and on the blog). What exactly does this represent and how is it related to star light?
4. These questions on time and space will require a bit of research to complete.
a. What is the current Greenwich Mean Time (GMT) and how is it different from the current time where we are?
b. What is the longitude and latitude of your current location. An approximate value for each is fine.
c. What is the current Julian Day (JD)?
d. What calendar are we currently using in the US?
